5,7-dihydroxy-3',4',6-trimethoxyflavone, commonly known as eupatilin, is a
traditional Asian medicinal plant, which is mainly used for the treatment of
gastritis, as well as its use as an anti-inflammatory agent. Eupatilin is a
bioactive compound; however, its effects on osteosarcoma (OS) have remained to be
elucidated. Therefore, the present study aimed to investigate the effects of
eupatilin on this malignant bone tumor, using the U-2 OS cell line. The
experimental results revealed that eupatilin inhibited U-2 OS cell growth in a
concentration-dependent manner and induced G2/M phase cell cycle arrest and
apoptosis. Additionally, western blot analysis indicated that eupatilin was able
to trigger the mitochondrial apoptotic pathway, demonstrated by the enhanced
Bax/B cell lymphoma-2 ratio, decrease in mitochondrial membrane potential,
release of cytochrome c, caspase-3 and -9 activation and
poly(ADP-ribose)polymerase cleavage detected in the U-2 OS cells. These results
indicated that eupatilin was able to inhibit U-2 OS cancer cell proliferation by
the induction of apoptosis via the mitochondrial intrinsic pathway. Eupatilin may
therefore represent a novel anticancer drug for use in the treatment of
osteosarcoma.
